Abstract
PURPOSE: In a speed controller for switching the operation speeds of cylinders, to simplify its piping and to make it small-sized and highly efficient by a method wherein the speed controller is constituted in such a manner that a check valve and a flow rate adjuster are integrally incorporated therein.
CONSTITUTION: The speed controller 9 is arranged midway in a passage 15 and operates such that the displacement of compressed air into a head chamber 3a in a vertical cylinder 3 is increased in association with the operation of a horizontal cylinder to thereby accelerate the vertical reciprocating motions of the piston of the vertical cylinder 3. Thd speed controller 9 includes a main body 17 within which there are provided control ports 20 and 21 connected to passages 12 and 13, respectively, and a main communication passage 22 for establishing communication between a valve port 18 and a cylinder port 19. The main passage 22 is in communication with both of the control ports 20 and 21 through a control passage 23 which is in communication with the main communication passage 22 through an auxiliary passage 24. Further, within a cylinder 17 fitted in the control passage 23 there is fitted a valve section having pistons 29 and 30 at both ends and a spool 32 at the center thereof.
